The authors have addressed developments of SMES system effective for power system stabilizing control. Focused on control logics that can be used to efficiently regulate SMES, a number of unique control logics were devised by combining the popularly used power deviation (ΔP) of a generator with the angular velocity deviation (Δw) of a generator or the phase correction. We practiced a digital simulation analysis for the created logics under both conditions of one- and multi-machine infinite-bus systems using the Y-method power system dynamics analysis program, which was compiled by the CRIEPI. As a result, it was revealed that the rated capacity and the amount stored energy of SMES necessary for power system stabilizing can be reduced by approximately 3 to 5% when compared to that obtained by employing the conventionally used ΔP control method alone.
